[0060] refer to Figures 4A-4CIn at least one exemplary embodiment, the base 200 includes a bottom wall 400, a first sidewall 405 extending from the periphery of the bottom wall 400, a support wall 410, and a second sidewall 415. The first sidewall 405 and the second sidewall 415 extend from respective ends of the support wall 410. For example, the first sidewall 405 and the second sidewall 415 may be perpendicular to or substantially perpendicular to the support wall 410. The length of the first sidewall 405 may be greater than the length of the second sidewall 415. In other exemplary embodiments, the length of the second sidewall 415 may be equal to or greater than the length of the first sidewall 405.

[0061] In at least one exemplary embodiment, a first sidewall 405, a support wall 410, and a second sidewall 415 define a recess 420.

Figure 7B As shown, the protrusion 525 may be configured to contact the top surface of the vent 215 (e.g., the top surface of the top 600). In at least one exemplary embodiment, a second side 510 of the top wall 500 of the cover 205, each of the plurality of ribs 530, the protrusion 525, and the support wall 410 of the base 200 define a plurality of compartments 705. Each of the plurality of compartments 705 is fluidly coupled between the gap 700 and the cavity 238 of the base 200. For example, each of the plurality of compartments 705 may be fluidly coupled to the cavity 238 via a plurality of side recesses 435.

[0076] Still referencing Figure 7A The surrounding environment can be in fluid communication with the interior of the filter device 210 through gaps 700, one or more compartments 705 and cavity 238.

[0077] refer to Figure 7B When the vent 215 is within the filter device 210, the surrounding environment can be in fluid communication with the vent 215 via the gap 700, one or more compartments 705, multiple side recesses 435, side openings 620, the space 615 of the second part 250, and the channel 625.

Figure 8B The second fluid passage is shown according to at least one exemplary embodiment. Figure 1A-1B Detailed cross-sectional view of the filtration system and electronic units.

[0079] refer to Figure 8A and Figure 8BIn at least one exemplary embodiment, the filtration system 105 is configured to be detachably coupled to the electronics unit 100. For example, the filtration system 105 may be threadedly coupled to the electronics unit 100 via a thread 630 using a vent 215. The thread 630 may be configured to engage with the inner surface of the cavity 810 defined by the electronics unit 100. In other exemplary embodiments, the filtration system 105 may be detachably coupled to the cavity 810 of the electronics unit 100 via a friction fit, snap-fit ​​fit, or other engagement mechanism or component.

[0080] As referenced above Figure 3 The filtration system 105 may include a gasket 255. In at least one exemplary embodiment, the gasket 255 surrounds a first portion 245 of the vent 215, adjacent to a second portion 250. For example, the gasket 255 contacts at least a portion of the lower surface of the bottom 605 of the second portion 250 of the vent 215. Figures 8A-8B As shown, gasket 255 is located between filter system 105 and electronic unit 100 and is configured to create a fluid seal.

[0081] In at least one exemplary embodiment, the filtration system 105 is configured to create at least two fluid passages. (Reference) Figure 8A The inner surface of the third sidewall 515 of the cover 205, the second sidewall 510 of the top wall 500 of the cover 205, the outer surface of the second sidewall 415 of the base 200, and the top surface of the support wall 410 define the first fluid passage 800.

[0082] In at least one exemplary embodiment, the first fluid passage 800 is configured to guide liquid and / or solid particles entering the filtration system 105 from the surrounding environment away from the electronic unit 100. For example, liquid and / or solid particles may enter the filtration system 105 through a gap 700. The first fluid passage 800 guides the liquid and / or solid particles from the gap 700 into a compartment 705 by gravity, and then toward the opposite end or bottom of the filtration system 105, such that the liquid and / or solid particles exit the filtration system 105 through one of the compartments 705 at the opposite end of the filtration system 105 and the gap 700. Liquid and / or solid particles within the first fluid passage 800 may be guided to the bottom of the filtration system 105 through each of the compartments 705 defined by a plurality of ribs 530 and protrusions 525.

[0083] In at least one exemplary embodiment, the first fluid passage 800 prevents or substantially prevents liquid and / or solid particles (such as dust) from entering the vent 215, thus preventing the vent from being blocked. For example, if liquid and / or solid particles accumulate at or within the vent 215, the vent 215 may become blocked and impede airflow into and out of the electronics unit 100. Such blockage can create pressure, such as a vacuum, within the electronics unit 100, which can cause the electronics unit 100 to malfunction.

[0084] refer to Figure 8B The inner surface of the third sidewall 515 of the cover 205, the second side 510 of the top wall 500 of the cover 205, the outer surface of the second sidewall 415, the top surface of the support wall 410, and the inner surface of the first sidewall 405 define at least a portion of the second fluid passage 805. The second fluid passage 805 may be an air passage in fluid communication with the electronic unit 100. For example, the second fluid passage 805 may be configured to guide air from the surrounding environment through the vent 215 and into the electronic unit 100. The second fluid passage 805 defines a labyrinth through which air can enter but liquid and / or solid particles cannot. For example, liquid and / or solid particles may fall into the filtration system 105, for example, through the first fluid passage 800, before reaching the vent 215.

[0085] In at least one exemplary embodiment, the second fluid passage 805 guides air through the gap 700, the compartment 705, and the side recess 435 toward the vent 215. Air can enter the vent 215 through the side opening 620, pass through the space 615 and the channel 625, and enter the electronics unit 100 through the cavity 810. As described above, the vent 215 may include a membrane filter configured to prevent liquid and / or solid particles from entering the channel 625 and / or the electronics unit 100. For example, at least a portion of the bottom 605 of the vent 215 may include a membrane filter. In other exemplary embodiments, the membrane filter may be within the channel 625 and / or the cavity 810. In yet another exemplary embodiment, the membrane filter may be within the filtration device 210, for example, as... Figure 7B As shown, within the filtration device 210. For example, a membrane filter may be located within the cavity 238 and / or coupled to the inner surface of the base 200 or the cover 205. In such an exemplary embodiment, the membrane filter may replace the vent 215.

[0086] In at least one exemplary embodiment, the second fluid passage 805 may also flow in reverse. For example, air may be discharged from the electronic unit 100 through the vent 215 and filter device 210 of the filtration system 105. This allows the electronic unit 100 to "breathe," enabling air to enter and exit the electronic unit 100.

[0087] Figure 9 This is a detailed cross-sectional view of another filtering system and electronic unit according to at least one exemplary embodiment.

[0088] refer to Figure 9 In at least one exemplary embodiment, the filtration system 903 may be integrated into the electronic unit 900.

The cavity 910 is configured to be in fluid communication with the interior of the electronic unit 900. The at least one protrusion 905 may be a cylindrical or substantially cylindrical protrusion surrounding the cavity 910. In other exemplary embodiments, the at least one protrusion 905 may include a first protrusion adjacent to the cavity 910 and a second protrusion opposite to the first protrusion and adjacent to the cavity 910.

[0089] In at least one exemplary embodiment, the cavity 910 is configured to house a filter (e.g., the one described above). Figure 3 and 6A -8B discusses at least a portion of the vent 215. In at least one exemplary embodiment, at least one protrusion 905 defines a recessed space 915 adjacent to the cavity 910. The perimeter, width, or diameter of the recessed space 915 may be greater than the perimeter, width, or diameter of the cavity 910. The cavity 910 may be configured to receive a first portion 245 of the vent 215, and the recessed space 915 may be configured to receive a second portion 250 of the vent 215. For example, the second portion 250 of the vent 215 may be located within the recessed space 915 such that the bottom surface of the bottom 605 contacts the surface of the electronic unit 900 surrounding the cavity 910, and the top surface of the top 600 of the vent 215 is flush with the outer surface of at least one protrusion 905.

[0090] In at least one exemplary embodiment, a cover 920 is coupled to at least one protrusion 905. The cover includes a top wall 925 and a side wall 930 extending from the periphery of the top wall 925. The side wall 930 may be configured to couple the cover 920 to the at least one protrusion 905. In at least one exemplary embodiment, the cover 920 includes at least one engaging member 935 extending from an end of the side wall 930 opposite to the top wall 925. For example, the at least one engaging member 935 may extend from an end of the side wall 930 perpendicular to the side wall 930 and parallel to the top wall 925. The at least one engaging member 935 may be configured to engage the exterior of the at least one protrusion 905, for example, by a snap-fit ​​or other engagement mechanism, to secure the cover 920 to the electronic unit 900. The at least one engaging member 935 may be a single cylindrical member extending around the periphery of the side wall 930. In other exemplary embodiments, the at least one engaging member 935 may be a plurality of discrete members extending from the periphery of the side wall 930.

[0091] In at least one exemplary embodiment, at least one protrusion 940 extends from the inner surface of the top wall 925 of the cover 920. The at least one protrusion 940 is configured to extend toward the vent 215 and the electronic unit 900 when the cover 920 is coupled to the electronic unit 900. The cover also defines at least one recess 945 adjacent to the at least one protrusion 940.

[0092] In at least one exemplary embodiment, the filtration system 903 defines at least two fluid passages. For example, the filtration system 903 defines a first fluid passage, as described above with reference to... Figure 8A The first fluid passage 800 is described, configured to guide liquid and / or solid particles entering the filtration system 903 away from the vent 215 and out of the filtration system 903. The first fluid passage may be defined by the inner surface of the sidewall 930, the outer surface of at least one protrusion 905, and the inner surface of the top wall 925 of the cover 920. Liquid and / or solid particles may be guided downwards by gravity along the inner surface of the top wall 925, along at least one protrusion 940, and through at least one recess 945. Because the liquid and / or solid particles are guided along the inner surface of the cover 920, liquid and / or solid particles are prevented from entering the electronic unit 900 through the vent 215. Liquid and / or solid particles may be discharged through the bottom of the cover 920.

[0093] In at least one exemplary embodiment, the filtration system 903 defines a second fluid passage, similar to the reference described above. Figure 8B The second fluid passage 805 is described, configured to allow air to enter and exit the electronic unit 900. The second fluid passage may be defined by the inner surface of the sidewall 930, the outer surface of at least one protrusion 905, at least a portion of the inner surface of the top wall 925 of the cover 920, and a recessed space 915. Air may be... (The sentence is incomplete and requires further context to translate accurately.) Figure 8B In a similar or analogous manner, air enters and exits the vent 215 and the electronic unit 900 via the recessed space 915. For example, air may enter the vent 215 from the recessed space 915 through the side opening 620, such that the air is guided through the space 615, the membrane filter, the channel 625, the cavity 910, and into the electronic unit 900.
